I can't figure out why none of my wifi clients will work with 3rd party DNS servers.
Background:
I'm renting an apartment in Kiev, Ukraine and a TP-LINK TL-WR741ND router was provided for me. The router is ISP-branded, with "Kyivstar" printed on top. First thing I did was a factory reset and set up the SSID and within a moment I was online with my 2 iOS devices, Android tablet, and Win7 laptop.
Everything worked fine, but I want to use Google's DNS servers.
I can see the Kyivstar DNS servers used by the router (193.41.63.181 and 193.41.63.182) on the main status page at http://192.168.1.1 in the WAN section. See the simulator here: http://www.tp-link.com/resources/sim..._4.2/index.htm
But unlike in the simulator's Network>WAN settings, my router doesn't have the checkbox labeled "Use these DNS servers" or the 2 fields below it for primary and secondary DNS server addresses.
Maybe that option isn't available in my router because of old firmware, but my router also doesn't have the Firmware Upgrade page under the System Tools menu. I checked carefully and there are no other differences (well, my router's UI is in Russian). But obviously there are some restrictions in place on this device vs. a standard TL-WR741ND.
No big deal, I can specify DNS servers in each client. Nope, no such luck. Using static DNS servers only works if the primary or secondary server is one of the following:
Could it be something with how the router handles UDP traffic? Torrents work fine. Disabling the SPI Firewall didn't help. Nothing in the router logs. Fully disabling DHCP and using static IPs in the clients didn't help. Can the router specifically block 3rd party DNS responses? Is there something I should look for in the Windows event viewer?
I will try to get another router to test but hopefully someone knows what the issue could be.
Thanks in advance!
